Proceedings of the IOARP International Conference on Communication and Networks (ICCN 2015) 95 1. Introduction The last few decades have observed tremendous changes in communication technologies. From 1G to 4G, the area of telecommunications has seen a number of improvements along with improved performance are developed. All previous generations are different from each other due to their improved specifications. 5G technology is on its way to change the whole telecommunication history in near future . Looking back at the development of the wireless communication networks from 1G to 4G, which lead the communication history at high edge. The evolution of wireless communication is stated as “generation”, started from early 1980’s known as first generation 1G mobile wireless communication system. This generation was based on analog technology known as Advance Mobile Phone Service (AMPS). 1G has channel capacity of 30 KHz and frequency band was 824- 894 MHz . This generation uses circuit switching and totally designed for voice calls without data services. After 1G, in 1990’s the 2G second generation mobile communication system was the first digital cellular system launched. This generation uses two digital modulation schemes: TDMA (time division multiple access) and CDMA (code division multiple access). Three types of advancements in wireless communication system are 2G, 2.5G and 2.75G. These are family members of second generation . 2G has speed of 64 kbps with bandwidth of 30 to 200 KHz. Next to 2G, 2.5G system uses packet switched and circuit switched domain and provide data rate up to 144 kbps . The third generation 3G technology introduced in the year 2000, is seen more as pre 4G. Packet Switching is the technique for data sending in 3G networks. For video chatting and for high speed internet service, this network allows 15-20MHz bandwidth at a range of 2100MHz . The evolution of GSM is also a part of this generation. 3G, 3.5G and 3.75G are also family member of this generation.
